Windows Phone 8 CommunicationException 远程服务器返回错误:NotFound

我想问一个一直让我疯狂的问题@_@我为Windows Phone 8制作了一个应用程序，可以从wcf服务中检索数据。幸运的是，我的办公室同事为我提供了服务。但是，当我使用该服务时，我收到此错误。

在这里和那里搜索后，我得到了这篇好文章。http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj684580（v=vs.105）.aspx

但是，我读了它，仍然不明白。为什么？因为我的服务是用 C# 类编写的，而不是作为 Web 服务编写的。所以我找不到 IIS 服务。

这是我生成数据的代码。

public PurchaseInvoiceMainPage()
        {
            InitializeComponent();
            this.Loaded += new RoutedEventHandler(purchaseInvoice_Loaded);
        }
        private void purchaseInvoice_Loaded(object sender, RoutedEventArgs e)
        {
            NavcoreNavfinServiceClient client = new NavcoreNavfinServiceClient();
            client.GetAllCompleted += new EventHandler<GetAllCompletedEventArgs>(client_getAllPurchaseInvoice);
            client.GetAllAsync("509A7214-D3A9-47E7-9BB4-232E670ED650");
        }
        private void client_getAllPurchaseInvoice(object sender, GetAllCompletedEventArgs e)
        {
            if (e.Error == null)
            {
                purchaseDataList.ItemsSource = e.Result;
            }
        }

而且，这是我的服务，它返回结果。

public System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> EndGetAll(System.IAsyncResult result) {
                object[] _args = new object[0];
                System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> _result = ((System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice>)(base.EndInvoke("GetAll", _args, result)));
                return _result;
            }

我在这一行上得到了例外。

System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> _result = ((System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice>)(base.EndInvoke("GetAll", _args, result)));

我使用了许多我发现的技巧，从扩大最大字节数等开始。它仍然不起作用。有人请帮助我。我真的很困惑TT_TT

这是我使用的服务。

你们所有人的任何回答都会让我思考更多，请给出答案。
